† The three major scales (evidence, context, facilitation) are averages of their constituent subscales, thus subscales are equally weighted. ‡ Cronbach's alpha for a revised context scale after eliminating the general resources subscale was 0.87. †† Cronbach's alpha for a revised evidence scale based on just the research evidence and clinical experience subscales was 0.83. Alpha numeric information in parentheses is item numbers, which are used in the example survey [see Additional file 1].
